Age differences in autonomic variables during sleep.

Relationships of autonomic variables and sleep were assessed in men and women at two age levels (18 to 23 and 57 to 71 years) to check for alleged associations between physiological arousal and age-related sleep disturbance. Heart rate, although relatively high at the upper age level, was unrelated to sleep measures. For the most part, underarousal rather than hyperarousal characterized older sleepers. Women's body temperature declined significantly with age. Vasoconstrictions, which were more frequent in young adults, showed some association with better sleep. The earlier the overnight temperature nadir, the more wakefulness after sleep onset. Together with other studies, this suggests that an age-related phase advance in the temperature rhythm disrupts sleep. These results are at odds with the view that sympathetic hyperactivity associated with elevated plasma norepinephrine causes age-related sleep disturbance.

Effects of age on auditory awakening thresholds.

Auditory awakening thresholds ( AATs ) were assessed in sleeping men and women at three age levels (18 to 25, 40 to 48, and 52 to 71 years) with a procedure that employed a 5-sec tone in accordance with the up-and-down method. Although age was less influential than individual differences in predicting AAT levels, there was a significant and substantial AAT decline from early adulthood to later life in Sleep Stages 4, 2, and REM. With no variation by sex, this progressive decline was apparent by the 40s in Stages 4 and 2 and was sharpest from one age level to another in Stage 4. Decline was more gradual and delayed in REM, probably because of a sampling artifact based on stimulus incorporation in dreams. These findings help to explain increased sleep disturbance in the later years as a result of diminished intensity of sleep, which makes sleep more difficult to sustain.

Evaluation of a yearlong reality orientation program.

The effectiveness of Reality Orientation (RO) as treatment for disorientation and behavioral deficits in institutionalized elderly adults was assessed over a one-year period, with evaluations at 6-month intervals. Residents of a home for the aged with varying degrees of disorientation and disability were treated with a 24-hour RO program and were compared with a control group. A subsample of disoriented residents also attended RO classes and was compared with controls. Treatment effects were assessed with a Mental Status Questionnaire (MSQ) and ratings of Activities of Daily Living (ADL) and interpersonal behaviors. Compared with controls, who showed deterioration, the subsample attending RO classes showed slight, statistically significant improvement on the MSQ after 6 months. There was no favorable effect on ADL or other measures. Comparisons with other studies suggest that advanced age, severity of disorientation and disability limit the effectiveness of RO.

Age differences in dreams. II: Distortion and other variables.

Age-related change in manifest dream content was assessed in dreams recalled from REM sleep by fifty-eight men aged twenty-seven to sixty-four and in dreams recalled from sleep at home. There was evidence of a small-age-related decline in dream distortion (bizarreness) and family-related content, with family-related content most prominent from ages thirty-five to fifty-five. Overall the effect of increasing age on dream content is slight.

Locus of control, perceived constraint and morale among institutionalized aged.

Examination of the relationship between locus of control and life satisfaction was prompted by a report that external locus of control (belief in the controlling influence of others) promotes good morale for the institutionalized elderly. Contrary to this report, life satisfaction of fifty-six institutionalized elderly women was associated with internality (belief in personal influence). Life satisfaction was also inversely related to perception of institutional constraint (r = -.61), which was its most powerful determinant.

Sleep in young and old rats.

Five young rats, age 152--175 days, and six old rats, age 782--801 days, all of the F-344 strain, were compared by electronic methods for amplitude of slow wave activity during sleep and for other sleep parameters. Unlike humans, who show a pronounced loss of slow wave activity with advanced age, no significant difference in delta activity could be detected between young and old rats. Several hypotheses about the species difference were reviewed. Young and old rats, however, did show several differences in other sleep parameters which parallel those observed in humans. These age-related changes were a moderate decrease in the percent of total sleep time spent in paradoxical sleep, a decrease in the length of sleep bouts, an increase in the number of sleep bouts, and a decrease in the amplitude of the diurnal rhythm of sleep.

Is age becoming irrelevant? An exploratory study of perceived age norms.

To check on impressionistic assertions that the United States is becoming an "age-irrelevant society," a quota sample of white-collar and blue-collar men and women (ages eighteen to seventy; N = 462) was studied with a questionnaire that asked for designation of the most suitable ages for various role transitions and age-related attributes. The findings converged with pertinent recent reports from more representative samples. Comparisons with findings in the 1950s indicated loosening of the norms, but with continuing adherence to a prescriptive timetable and with persistent socio-economic differences. These results challenge the notion of age-irrelevance.

Age differences in dreams. I: men's dreams and thematic apperceptive fantasy.

Is there a covert, middle-age shift towards passivity and lowered ego energy? Age differences were investigated in dreams recalled from REM sleep by fifty-eight well-educated men age twenty-seven to sixty-four, and also in their TAT stories and dreams recalled from sleep at home. There was no confirmation of previous findings, although there was evidence of a slight age-related decline of aggression in dreams. These results raise the possibility that previous findings reflect cohort differences rather than age changes. Dreams and TAT stories failed to correlate sufficiently to warrant any assumption that they are interchangeable or that they tap covert processes.
